Read the following introductory paragraph, which is missing a hook:
Light from the sun hits Earth and warms the planet. The warm soil and water then release some of that heat back
into the air. Some of it escapes into space, and some of it is caught and held by gases in the atmosphere. This heat
trapping process is called the greenhouse effect, after what the windows in a greenhouse or a car do with solar
radiation they let the light move in and out, but trap a lot of the heat inside.
Which option below makes the most effective hook?
-
There is now overwhelming scientific consensus that climate change is happening - the average temperature of
the Earth's surface increased by about 1.4°F over the 20th century, with two thirds of it happening since 1980.
It is ironic that the greenhouse effect is named after a place where plants grow, because it is going to destroy
life on Earth.

I remember playing in snowdrifts higher than my head when I was a kid. My kids have never had that joy. It
doesn't snow much here anymore. Because of global warming, it probably never will.
For billions of years, the greenhouse effect was the best friend to life on Earth. Without it, the average global
air temperature would be barely above 0°F. This is how it works.
